In most cases, if you want to sell LED products on Amazon, you need to certify your products. This means that you need to provide relevant certification documents for your products, such as CE certification or ROHS certification, to prove that your products meet safety and environmental standards. If you do not have these certifications, your products may be banned from sale by Amazon, or your account may be suspended or cancelled. Therefore, if you want to sell LED products on Amazon, it is best to confirm whether your products need certification and make sure you have the corresponding certification documents.
